Torpedo Car Level Measurement 
MWS-10RF-1

The MWS-10RF-1 is an FM-CW Microwave Range Finder consisting of a controller and an antenna. The antenna can be installed in the high temperature area, while the controller can remain in a normal temperature area via waveguide. High temperature measurement can be taken without the need for additional cooling devices.
Installed on the casting floor, the microwaves transmitted from the controller travel to the antenna via waveguide, and are emitted through the antenna, hitting the surface of the molten iron. The microwaves are then returned to the controller via the same route, continuously measuring the level of the torpedo car from empty to full. Double reflected microwaves will not be received by the antenna due to the utilization of rotary microwaves.
This proven system has been installed in major steel companies all around the world.

Features

  • Unaffected by adverse conditions
    Microwaves are unaffected by heat, flames, and air particles.
    The antenna can be used in the high temperature area, while the controller can be used in the normal temperature area, without additional special cooling systems.
    The antenna and the controller can be connected via waveguide, which can be bent 90 degrees.
  • High accuracy and reliability
    ±10mm accuracy (Target: Metallic plate)
    Employs the rotary microwave technique: false measurements caused by double-reflected waves are eliminated.
    Unnecessary reflections can be eliminated by the filter function.
  • The operational state is shown on your personal computer
    It displays a FFT spectrum, the received signal and various preset values.
    The received signal, FFT spectrum and the measurement trend are continually displayed. This displayed data can be recorded and reviewed in real or accelerated time.
    Use of the recording and reviewing capabilities allows the system parameters to be optimized offline.
    The controller outputs the internal temperature and any abnormal conditions (i.e. a lowering of received signal power, rising temperature in the controller and communication failures), which can be shown on the display (optional).
  • Convenient built-in functions
    A reference point and the required range are easily preset.
    Compatible for use with a personal computer.
    Wide range of power supply 90∼240V, 50/60Hz.
    Communicates with a Personal Computer by RS-232C.
    4-20mA, analogue output.
    RS-422 digital output terminals (distance, receiving power level, temperature and alarm).
  • Comprehensive stand alone system
    No additional hardware/software is needed as all signal processing is done in the controller.
  • Lightweight and compact
    Portable (controller: 5.7kg, antenna: 3.3kg).
    Easy installation.
  • Easily adapts to the customers specific requirements
    The hardware and software can be easily adapted to the customers requirements.
